Design of USB Type CAN Bus Debugger Based on STM32

In view of the shortcoming of traditional debugging tools,a new approach of CAN bus debugging tool was designed.The system is based on ARM Cortex-M3 kernel STM32f107RBT6 for controller core,and has bridged the CAN bus and USB bus.User can adopt PC to communicate with the controller via the USB interface,to complete CAN bus data receiving and sending.The system can provide a new way for debugging equipment engineering staff.
